If by clever you mean "egregious hack", I can.

- First, dup your working copy and reindent all the files.

- Write a script that iterates over all the files in your working copy.

- Run blame on each file, then, starting with the first user, make all
whitespace changes to the file for lines that that user is blamed for
(by pulling each line from the duped and reindented working copy).

- Commit as that user (you'll have to do something to work out the

- Repeat until you've committed all whitespace changes to the file.

- Move on to the next file.
